iMac G3 350 video is offset

This seems like it would be a simple problem, but on my iMac the video is moved to the left 1 to 2 inches. On a normal computer this wouldn’t be a problem I would just use the position settings and everything would be fixed. But on the Mac this is of course impossible because there is no knob to do this. So my question is, is there any way to make the video from my x server move over to the right about 2 inches? Thanks in Advance, Cameron
